Application filed pctober 10,1904. Serial No 227,903.

To all Ii /mm if may concern.-

Be it known that we, FRANK S. Snmrnna and {aunties l. TURNER, citizens of the United States, residing at Newcastle, in the county of Lawrence and State of Pennsylvania, haveinvented certain new and useful Improvements in Uar-(buplers; and we do declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in theart to which itappertains to make and use the same.

This invention relates to improvements in car-couplers.

he object ofithe invention is to provide an automaticall,voperating car-coupler the operative parts of which are on the outside, thereby obviating the necessity of providing a recessed orchamlalred draw-bar or ccmplerhead to receive said parts and permitting the use of a strong, durable, and solid construction of draw and head.

A further object is to provide a coupler so constructed and arranged that the knuckle pivot-pin will be relieved of the entire stress or pull, said stress being distributed between said pivot-pin and the lock-pin of the coupler.

With these and other objects in view the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particulary pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a top plan view of a coupler and draw-bar embodying the. invention, showing in full lines the position of the knuckle when coupled and in dotted lines the position of the same when uncoupled and ready to be engaged by the coupler of the next car. Fig. 2 is a bottom plan view of the same. Fig. 3 is a longitudinal vertical sectional view on the line 3 3 of Fig. 1 looking in the direction of the. arrow, theparts being shown in position ready for coupling. Fig. 4 is a detail perspective View of the knuckle removed from the couplerhead. Fig. 5 is a similar view of the locking-pin.

Referring more particularly to the drawcoupled position.

ings, 1 denotes the draw-bar, on the outer end of which is formed a draw-head or coupler which is in the Form of the Jaime-y type, and consists of a fixed jaw 3 and a pivoted jaw or knuckle, 4:, said knuckle being connected to a head 2 by means of a pivot-pin The knuckle 4 has formed thereon upper and lower inwardly-projecting tailpicces 6 and 7. The upper tailpiece 6 is in the form of a hook, which when said knuckle is in coupled position is adapted to engage the lug 8, formed on the upper side of the coupler-head. The lower tailpiece T is adapted to be engaged with the lug S), formed on the lower side of said coupler-head, when the knuckle is in a The engagement of said i tailpieces 6 and 7 with the lugs 8 and 9 liniits the inward movement of the knuckle when the same is brought to a coupled position.

In the outer end of the d raw-bar 1 is formed a vertically-disposed rectangular aperture 10, in which is arranged a rectangular lockingpin 12. Said pin is provided with an offset head 13, whereby the same is prevented from slipping through said aperture 10. The corner of said locking-pin adjacent to the upper tailpiece 6 of the knuckle is beveled or cut away, as shown at 14, so that when said pin is elevated in the aperture 10 said tailpiece is permitted to be moved past said pin, when the knuckle & is brought to a coupled or un coupled position. \Vhen said knuckle is in an uncoupled position, the offset head of the pin 12 is adapted to rest upon the hook-shaped end of the upper tailpiece 6, which supports said pin in an elevated position until said knuckle is moved to a coupled position, at which time the tailpiece (5 will be swung from beneath the offset head of said pin, thereby permitting the latter to drop into position upon said draw-bar, thus automatically locking the knuckle in its coupled position.

On the end of the conpler-heinl 2, adjacent to the pivotal connection of the knuckle therewith, is formed a lateral offset or projection 15, which is adapted to be engaged by said knuckle when the same is swung to an uncoupled position,'thereby limiting the outstops, whereby the inward movement of the ward movement of the same, thus preventing l the knuckle of the entire stress or strain of the knuckle from being opened too far. On 1 the cars.
